You wanna talk about kludges? Let's talk about kludges.
svndumpfilter is kludge. Nice itch, wrong scratch.

That said, you are correct to say that it is not true that a dumpfile
must be applied to an empty repository. As you noted, incremental
dumps (ala 'svnadmin dump -rX:Y --incremental') do not contain a full
"history diff", or at least that "diff" is not against an empty
history.
